DCS

Description

DCS (Departure Control System) is an environment simulating airline departure control operations. It evaluates agents on multi-turn conversations with simulated passengers, requiring information lookup and customer service responses. Currently implements Phase 1 with 5 basic lookup tasks; designed to scale to 75 tasks across 8 phases.

Capabilities

Airline operations simulation
Multi-turn passenger conversation handling
Flight information lookup and retrieval
Customer service response generation

Compute Requirements

Agents are given a standard environment with no sandbox or file system access.

License

ORLv1.

Tasks

There is one split in this environment:

test: 5 tasks (Phase 1)

Tasks cover: departure time queries, seat availability, booking confirmation, flight route information, and flight listing.

Reward Structure

This is a multi-turn conversational environment. The agent uses read-only tools to gather information, then responds via the respond tool. A user simulator (GPT-4o) plays the passenger role. Reward is calculated as: r_action × r_output where r_action checks database state correctness and r_output checks expected phrase coverage (0.0 to 1.0).

Data

Data consists of JSON files (flights.json, passengers.json, seat_maps.json, baggage.json) containing simulated airline data: 1 flight (AB123 JFK→LAX), 20 passengers, and 20 seats. Data is stored in the repository.

Tools

Tool	Description
`list_flights`	List all flights.
`get_flight_details`	Get detailed flight info.
`list_seats`	Show seat map with availability.
`get_passenger_details`	Look up passenger by PNR.
`respond`	Respond to passenger (triggers user simulator).

Time Horizon

Multi-turn. Agents gather information and respond to simulated passengers across multiple conversation turns.

Other Environment Requirements

OpenAI API key required for user simulation. Pass via secrets={"openai_api_key": "..."}.

Safety

Agents in DCS simulate airline customer service in a standard environment. The environment does not present direct safety risks.
